In this article, Joanne VanAuken says the recent formation of the Voice over IP Security Alliance (VOIPSA) may help increase VoIP security by increasing security awareness and providing free testing tools. While VoIP technology is advancing toward becoming a viable and potentially critical infrastructure for businesses and governments, it also carries the threat of hacking and eavesdropping. Application-level attacks are inevitable and voice spam is also a legitimate worry. If not implemented and secured, VoIP technology will open networks and organizations to increased risk. Ms. VanAuken hopes the VOIPSA will gain acceptance in the security community through vendor collaboration.
